  --------------------------------------------------------------------------

    This function returns the local user's printer setup string for a
    shared printer, which was set via function FE02h.

       Notes:         This function is called with a redirection list
                      index in BX; this index value may be determined by
                      calling of function 5F02h (Get Redirection List
                      Entry).

                      The setup string will not be longer than 64 bytes.

                      This function is available only in DOS version 3.1
                      and later, and requires that the IBM PC Network or
                      Microsoft Networks program be running.

       Important:     Since the redirection index value may change between
                      the time the redirection list is scanned and this
                      function call is issued, you should call this
                      function immediately after calling Function 5F02h,
                      Get Redirection List Entry. (A call to function
                      5F03h (Redirect Device) or 5F04h (Cancel
                      Redirection) could cause the redirection list entry
                      to change.)
